* m68k: bvme6000: Convert to clocksource APIFinn Thain2019-03-251-16/+41
| | | | | | | | | Add a platform clocksource by adapting the existing arch_gettimeoffset implementation. Signed-off-by: Finn Thain <fthain@telegraphics.com.au> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

| | | | | | | | | The functions that implement arch_gettimeoffset are re-used by new clocksource drivers in subsequent patches. Signed-off-by: Finn Thain <fthain@telegraphics.com.au> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
* m68k: Call timer_interrupt() with interrupts disabledFinn Thain2019-03-251-10/+10
| | | | | | | | | | | | | | | Some platforms execute their timer handler with the interrupt priority level set below 6. That means the handler could be interrupted by another driver and this could lead to re-entry of the timer core. Avoid this by use of local_irq_save/restore for timer interrupt dispatch. This provides mutual exclusion around the timer interrupt flag access which is needed later in this series for the clocksource conversion.

* m68k: Remove unused set_clock_mmss() helpersArnd Bergmann2018-07-291-45/+0
| | | | | | | | | | | | | Commit 397ac99c6cef ("m68k: remove dead timer code") removed set_rtc_mmss() because it was unused in 2012. However, this was itself the only user of the mach_set_clock_mmss() callback and the many implementations of that callback, which are equally unused. This removes all of those as well.

* char/genrtc: remove m68k supportArnd Bergmann2016-06-041-1/+0
| | | | | | | | | | | | | | | | | The asm/rtc.h header is only used for the old gen_rtc driver that has been replaced by rtc-generic. According to Geert Uytterhoeven, nobody has used the old driver on m68k for a long time, so we can now just remove the header file and disallow the driver in Kconfig. All files that used to include asm/rtc.h are now changed so they include the headers that were used implicitly through asm/rtc.h.

* m68k: set arch_gettimeoffset directlyStephen Warren2012-12-241-5/+5
| | | | | | | | | | | | | | remove m68k's mach_gettimeoffset function pointer, and instead directly set the arch_gettimeoffset function pointer. This requires multiplying all function results by 1000, since the removed m68k_gettimeoffset() did this. Also, s/unsigned long/u32/ just to make the function prototypes exactly match that of arch_gettimeoffset.

* IRQ: Use the new typedef for interrupt handler function pointersDavid Howells2006-10-091-3/+3
| | | | | | | | | | | | | | | | Use the new typedef for interrupt handler function pointers rather than actually spelling out the full thing each time.

* [PATCH] m68k pt_regs fixesAl Viro2006-10-071-6/+6
| | | | | | | | | | | | | | | m68k_handle_int() split in two functions: __m68k_handle_int() takes pt_regs * and does set_irq_regs(); m68k_handle_int() doesn't get pt_regs *. Places where we used to call m68k_handle_int() recursively with the same pt_regs have simply lost the second argument, the rest is switched to __m68k_handle_int(). The rest of patch is just dropping pt_regs * where needed. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
